8 Claims.

This invention relates to a bomb ejector and it is one object of theinvention to provide an ejector adapted for use upon air craft forbombing ground troops or other targets or upon boats for ejecting depthbombs when attacked by submarines.

Another object of the invention is to provide a device of this typehaving a number of barrels or tubes from which bombs may besimultaneously ejected by means of a single ejecting mechanism.

barrels.

Another object of the invention is to so mount the barrels that theymaybe tilted vertically to angularly adjusted positions and also allowthe device to be swung about a vertical pivot to adjusted positions.

Another object of the invention is to guide movement of the bombsthrough the barrels and, in addition, prevent the bombs from prematurelysliding out of the barrels when the barrels are tilted to depress themuzzles.

In the accompanying drawing:

Fig. 1 is a side elevation of the improved bomb ejector.

Fig. 2 is a sectional view taken transversely through the barrels on theline 2-2 of Fig. 1.

i 3 is a sectional view on the line 3-3 of Fig. 1. i

Fig. 4 is a perspective view of a spacer placed between bombs. I

Fig. 5 is a perspective view of a bomb to be discharged from the gun.

This improved gun has a plurality of barrels I and, while three havebeen shown in the drawing, it is to be understood that any numberdesired may be employed. These barrels extend in side by sidesubstantially parallel relation to each other and are held in place bywelding, as shown at 2 in Figs. 2 and 3. The welds for holdin thebarrels to each other may extend the full length of the barrels or anumber may be provided in spaced relation to each other. In thepreferred arrangement, the barrels are disposed as shown in Figs. 2 and3, with one barrel resting upon a pair of lower barrels and disposedover space between the lower barrels.

To support the barrels, there has been provided a carriage 3swiveled toa base I so that the carriage may be swung above a vertical axis and thebarrels pointed in. the desired direction. Standards or brackets 5extend upwardly from the carriage in such spaced relation to each otherthat the barrels ma be disposed between the standards and, at theirupper ends, the standards carry bearings 6 to receive stub shafts iprojecting outwardly from the lower barrels. The barrels will thus bemounted for vertical tilting adjustment and may be disposed at a desiredangle when disdischarging bombs. Arcuate arms 8 constituting quadrantsare secured against outer sides. of the lower barrels and extenddownwardly and forwardly therefrom with their lower portions passingthrough openings 9 formed through the standards. These arms have scalemarkings l0 upon their outer side faces for observation by a crew memberwhen tilting the barrels to adjusted angle and set screws II areprovided to engage the quadrants and secure the barrels in a setposition.

The barrels are loaded with bombs l2 which are fed into rear ends of thebarrels one after another to be shifted forwardly so that they aresuccessively discharged from front ends of the barrels. Discs l3 areplaced between certain of the bombs and are formed with arms or tonguesH which project from the discs radially thereof and pass through slotsl5 formed longitudinally of the barrels the full length thereof. Whilediscs have been shown between certain of the and omitted between otherbombs, it is to be understood that a disc may be placed against the rearend of each bomb as it is fed into a barrel. The slots l5 are so locatedin the barrels that the tongues projecting through the same may havtheir end portons overlapped, as shown in Fig. 2, and thus permit thetongues to brace each other and also permit the bombs in the threebarrels to be simultaneously shifted longitudinally of the barrelstoward front ends thereof. Ribs l6 extend longitudinally through thebarrels to guide movement of the bombs and engage in notches ll formedin heads l8 at rear ends of the bombs. It is necessary to prevent thebombs from accidentally or prematurely moving out of front ends of thebarrels when the barrels are depressed and to .do this, spring strips I!are mounted in the barrels. These strips extend longitudinally of theforward end portions of the barrels and the bombs cannot move past saidsprings unless forced forwardly.

In order to shift the bombs forwardly through the barrels there has beenprovided discharge mechanism consisting of an endless mover 20 in theform of a sprocket chain extending longitudinally of the barrels underthe same and trained about sprocket wheels 2| which are rotatablymounted on shafts 22 supported in bearing arackets 23 depending from thelower barrels. The lower flight of the sprocket chain also en loses asprocket wheel 24 carried by the shaft )f a motor 25 mounted on thecarriage 3 and when the motor is running the sprocket chain will bemoved in such a direction that its upper flight moves forwardly and arms26 carried by and projecting upwardly from the upper flight of the chainwill engage the arms or tongues H of the discs l3 and move the bombsforwardly through the barrels. The bombs will thus be successivelyejected from the ends of the barrels and drop upon a target over whichthe air craft is flying or drop into the water OVer or close enough toan attack ing submarine to sink the submarine when they explode.
